     CONSTITUTION: At the moment when the reference frequency signal 2 is input, the timer of the microcomputer 1 itself is started and the timer is counted until the next pulse to the signal 2 is input. The count value of this timer and predetermined reference value are compared to discriminate the frequency of the signal 2. After the system reset, this operation is inserted after initialization of each condition, and the discrimination data of 50/60Hz determined here is stored in one bit of the memory 7. After that, the signal 2 is transferred to the main processing routine counting it.

Title: Extruded shape
Inventor: SATO AKIHIRO
IPC: E04B1/61
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide an extruded shape suitable for the frictional agitation welding by the rotation of a rotary body. SOLUTION: An end part of an extruded shape 150 is projected to a rib 153 side to form a thick-walled part 156. The thick-walled part 156 is projected to an extruded shape 160 orthogonal to the direction of extrusion for further welding to constitute a projecting part 157. The projecting part 157 is overlapped on the external surface side of a plate 161 of the extruded shape 160. A rib 163 in the vicinity of a frame is cut and removed. The width L2 of the projecting part 157 is equal to the width L1 of the thick-walled part. That is, the projecting part 157 corresponds to the thick-walled part 156. A tip of the projecting part 157 is inclined similar to the thick-walled part 156.  When the rotary body 70 is inserted and the frictional agitation welding is executed, a metal of the projecting part 157 or the like is fed into a gap 150c since the projecting part 157 is present above the gap 150c between end parts 150b, 160b of two extruded shapes 150, 160. The metal is also fed above the extruded shape 160. Thus, more excellent welding can be obtained as compared with the case where the thick-walled part 156 and the projecting part 157 are absent, or when only the projecting part is absent.

Title: Actuator mechanism for controlling rudder face with variable transmission ratio
Inventor: OKADA TOYOHISA
IPC: B64C13/24
Filed: 1988-03-09
Abstract: PURPOSE:To miniaturize and lighten while improve the durability of a servo actuator by providing the linking position variable means of an output rod to a link and making the operating angle ratio of a rudder face to a brake horse power variable. CONSTITUTION:As a servo actuator 12 is operated, a link 16 is tilted by means of an output shaft 12' and a controlling rudder face 10 is rotated centering around a hinge shaft 21 via a slotted hole 18, a slide pin 17, and a rod 19 to vary an operating steering angle. As a flying speed gets higher, the rod 19 of a motor-driven actuator 20 is tilted to the position of the imaginary line making the operating angle of the controlling rudder face 10 with respect to a brake horse power smaller. On the contrary, as the flying speed gets lower, the rod 19 is rotated to the position of the solid line, making the operating angle of the rudder face larger. In general, since aircraft has a large steering angle and small operating force at the time of low speed while having a small steering angle and large operating force at the time of high speed, the output of the servo actuator 12, particularly with respect to the maximum load at the time of the maximum speed, can be greatly reduced by such a structure.

Title: Power steering
Inventor: MOMIYAMA FUJIO
IPC: B62D5/087
Filed: 1983-03-30
Abstract: PURPOSE:To enhance steering characteristics by furnishing a sleeve moving oppositely to the direction, in which a control valve spool operates, by means of the reactive force to adjust the reactive force, by quickening communication of a pump with the power cylinder, and by preventing improper flow of pressure oil owing to delay in actuation of the spool. CONSTITUTION:A signal from a car speed sensor 68 puts an actuator 61 in operation to increase the throttling amount of a reactive force adjusting valve 58, which is interposed in a communication line 57 to connect the reactive force chambers 31, 32 provided on the right and left sides of a control valve, in accordance with the increase of the car speed. If a control valve spool 30 slides either to the right or left through the operation of steering wheel, the internal pressure in one of the reactive force chambers 31, 32 situated on the side toward which the sliding is made will rise. Because a slide sleeve 24 slides oppositely to the direction in which the spool 30 slides through the action of said rising pressure, communication of the sleeve 24 with ports 25, 26 and a spool groove 34 is made in a short time. Thus improper flow of pressure oil owing to delay in actuation of the spool 30 is prevented to ensure enhancement of the steering characteristics.
